Holder system for a drum

Abstract

A holder system for a drum includes a body, holding structure within the body defining an adjustable opening, a fastener threadedly received in the body and engageable with the holding structure, a holding rod received in the opening such as to be able to be moved linearly and to rotate with respect to the body. Clamping structure has a portion disposed within the body and is associated with the holding structure. A shaft is received by the clamping structure such that the shaft can rotate about an axis thereof and rotate with respect to the body. When the fastener moved to engage the holding structure, the opening reduces in size and thus causes the holding structure to prevent any movement of the holding rod and, substantially simultaneously, a portion of the holding structure engages a part of the clamping structure causing the clamping structure to prevent any movement of the shaft.

What is claimed is: 
     
       1. A holder system for a drum comprising:
 a body, 
 an upper holding member disposed within the body, 
 a lower holding member disposed within the body and coupled to the upper holding member to define an adjustable opening between the upper and lower holding members, 
 a fastener threadedly received in the body and engageable with a surface of the upper holding member, 
 a holding rod having a proximal end received in the opening such that when the holding rod is in an unsecured condition when the fastener is not engaged with the holding member, the holding rod can be moved linearly and be rotated with respect to the body, 
 a pin received in the body and associated with a surface of the lower holding member, 
 a resilient, generally cylindrical split ring fixed to the body, the split ring having an adjustable bore there-through, the pin being engaged with the split ring, 
 first and second clamping members having portions received in the bore of the split ring so as to be rotatable with respect to the body, and 
 a shaft received by the first and second clamping members such that in the unsecured condition, the shaft can rotate about a longitudinal axis thereof, and rotate with respect to the body, 
 wherein the holder system is constructed and arranged such that when the fastener is moved to engage the upper holding member, the upper holding member is pushed by the fastener causing the opening between the holding members to reduce in size and thus causing the holding members to clamp on and prevent any movement of the holding rod and, substantially simultaneously, the lower holding member pushes on the pin which causes the bore of the split ring to reduce in size causing the split ring to clamp on the clamping members to prevent any movement of the shaft, thereby defining a secured condition of the holding rod and shaft. 
 
     
     
       2. The holder system of  claim 1 , wherein the fastener is a key-bolt, a hex-bolt or a handle bolt. 
     
     
       3. The holder system of  claim 1 , wherein the split ring has opposing ends disposed in spaced relation with a gap there-between, and wherein reduction of a size of the gap causes reduction in the size of the bore of the split ring. 
     
     
       4. The holder system of  claim 1 , wherein the proximal end of the holding rod includes a removable stop having a surface constructed and arranged to engage surfaces of the holding members to prevent the holding rod to be removed from the holding members until the removable stop is removed. 
     
     
       5. The holder system of  claim 1 , wherein the body and the split ring include co-operating arc-shaped openings therein constructed and arranged to permit the shaft to rotate in a limited manner with respect to the body. 
     
     
       6. The holder system of  claim 5 , wherein the body has a body end defining a stop surface, and an end of at least one of the openings defining an opposing stop surface, the stop surfaces being constructed and arranged to engage a portion of the shaft to limit rotation of the shaft with respect to the body. 
     
     
       7. The holder system of  claim 1 , wherein the holding rod is configured as an L-rod. 
     
     
       8. The holder system of  claim 7 , further comprising a rod adapter fixed to a distal end of the holding rod, the rod adapter being constructed and arranged clamp upon the holding rod, the rod adapter including a 22.2 mm shaft. 
     
     
       9. The holder system of  claim 8 , further comprising a stop lock fixed to the distal end of the holding rod engaged with the rod adapter such ensure that once moved, the rod adapter can be again engaged with the stop lock and located at a position with respect to the holding rod defined by the location of the stop lock. 
     
     
       10. The holder system of  claim 7 , wherein a distal end of the L-rod has a diameter of 9.5 mm. 
     
     
       11. The holder system of  claim 7 , wherein a distal end of the L-rod has a diameter of 10.5 mm. 
     
     
       12. The holder system of  claim 7 , wherein a distal end of the L-rod has a diameter of 12.9 mm. 
     
     
       13. The holder system of  claim 1 , wherein a distal end of the holding rod has a diameter of 22.2 mm. 
     
     
       14. The holder system of  claim 13 , wherein the distal end and the proximal end of the holding rod is disposed on the same axis. 
     
     
       15. The holder system of  claim 13 , wherein the distal end of the holding rod is disposed at an angle of 45 degrees with respect to the proximal end thereof. 
     
     
       16. The holder system of  claim 1 , wherein the portions of the clamping members are generally half-cylindrical portions that cooperate to define a generally cylindrical structure that is received in the bore of the split ring, the generally cylindrical structure defining a shaft bore for receiving the shaft. 
     
     
       17. The holder system of  claim 16 , wherein the shaft is mounted with respect to the clamping members in the shaft bore such that the shaft is prevented from moving linearly with respect to the longitudinal axis thereof. 
     
     
       18. The holder system of  claim 1 , further comprising a stop lock mounted on the holding rod constructed and arranged to engage a portion of the body to define a mounting location of the body with respect to the holding rod. 
     
     
       19. A holder system for a drum comprising:
 a body, 
 holding structure disposed within the body to define an adjustable opening, 
 a fastener threadedly received in the body and engageable with the holding structure, 
 a holding rod having a proximal end received in the opening such that when the holding rod is in an unsecured condition when the fastener is not engaged with the holding structure, the holding rod can be moved linearly and be rotated with respect to the body, 
 clamping structure having a portion disposed within the body and being associated with the holding structure, and 
 a shaft received by the portion of the clamping structure such that in the unsecured condition, the shaft can rotate about a longitudinal axis thereof, and rotate with respect to the body, 
 wherein the holder system is constructed and arranged such that when the fastener moved to engage with the holding structure, the engagement causes the opening to reduce in size and thus causes the holding structure to clamp on and prevent any movement of the holding rod and, substantially simultaneously, a portion of the holding structure engages a part of the clamping structure causing the clamping structure to prevent any movement of the shaft, thereby defining a secured condition of the holding rod and shaft. 
 
     
     
       20. The holder system of  claim 19 , wherein the holding structure comprises:
 an upper holding member disposed within the body, 
 a lower holding member disposed within the body and coupled to the upper holding member to define the adjustable opening between the upper and lower holding members, and wherein the clamping structure comprises:

 first and second clamping members having portions received in the bore of the split ring so as to be rotatable with respect to the body, the first and second clamping members receiving the shaft, 
 wherein the holder system is constructed and arranged such that when the fastener is moved to engage the upper holding member, the upper holding member is pushed by the fastener causing the opening between the holding members to reduce in size and thus causing the holding members to clamp on and prevent any movement of the holding rod and, substantially simultaneously, the lower holding member pushes on the pin which causes the bore of the split ring to reduce in size causing the split ring to clamp on the clamping members to prevent any movement of the shaft, thereby defining a secured condition of the holding rod and shaft.
